"Two security vulnerabilities have been discovered in bozohttpd, a
small HTTP server.

CVE-2014-5015

Bozotic HTTP server (aka bozohttpd) before 201407081 truncates paths
when checking .htpasswd restrictions, which allows remote attackers to
bypass the HTTP authentication scheme and access restrictions via a
long path.

CVE-2015-8212

A flaw in CGI suffix handler support was found, if the -C option has
been used to setup a CGI handler, that could result in remote code
execution.

For Debian 7 'Wheezy', these problems have been fixed in version
20111118-1+deb7u1.

We recommend that you upgrade your bozohttpd packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
